查询词典 static friction

Friction and wear behaviors of Ti6Al4V alloys against GCr15 steel under dry sliding were investigated on high-speed pin-on-disc tribometer. Contact temperatures due to friction heat were measured by a thermocouple inserted into the hole of the Ti6Al4V pins. Morphology, composition and phase structure of the surface and subsurface for Ti6Al4V were examined by means of scanning electron microscopy, X-ray diffraction and transmission electron microscopy.

It was shown that the great variation of effective unit weight and angle of internal friction of soil could result in the increase of seepage failure probability of earth dams, the effect of variation of angle of internal friction of soil was greater, and the seepage failure probability of earth dams was sensitive to variability of dam seepage. In addition, the increase of water level in reservoir would also induce great increase of seepage failure probability of earth dams.

结果分析表明，坝体渗透破坏的概率随着土体有效重度和内摩擦角变异性的增加而增加，并且土体内摩擦角的变异性对坝体渗透破坏的影响较大，坝体渗透变异性对坝体渗透破坏的影响较大；另外，随着库水位的升高，坝体发生渗透破坏的概率也显著增加。
